Physics 12 Exam Two Name:__________________________________ MULTIPLE CHOICE. Circle the one alternative that best completes the statement or answers the question. Each question is worth 3 points. 1) A vertical wire carries a current straight down. To the east of this wire, the magnetic field points A) south. B) down. C) east. D) north. Use the right hand rule. Point your thumb down. Your fingers curl toward the south when you look on the east side. The answer is A. 2) A charged particle moves and experiences no magnetic force. From this we can conclude that A) the particle is moving at right angles to the magnetic field. B) no magnetic field exists in that region of space. C) the particle is moving parallel to the magnetic field. D) either no magnetic field exists or the particle is moving parallel to the field. Force on a moving charged particle is qvBsinθ. If the force is zero, then either B is zero, or sinθ is zero. The answer is D. 3) A current carrying loop of wire lies flat on a table top. When view...
